Rain washed out the Camping World Truck Series season opener as well as qualifying for the Nationwide Series opener on Friday at Daytona International Speedway. The Truck race will now run Saturday at 7 p.m. ET, after the completion of the Nationwide race, which begins at 1:15 p.m. ET. Before both races, the Cup Series will run its scheduled practice at 10:30 a.m. ET.

With the Nationwide field set by the rulebook, defending series champion Kyle Busch is on the pole for the Drive4COPD 300 with Carl Edwards on the outside of the front row.

Danica Patrick will start 15th in her first Nationwide Series race, while Cup veterans Greg Biffle and Tony Stewart made the 43-car field thanks to wins in 2009. 

The Truck race, which will have Jason White starting from the pole, will mark Nelson Piquet Jr.'s debut in the series, with the Brazilian set to start 22nd.

"This is a whole other ball of wax, and the car is not easy to drive," said Patrick ahead of her Nationwide Series debut. "There are a lot of really great drivers out there, really great teams, and everyone is running close. I'm glad to be out there."

The rain eventually stopped and the Truck Series race looked set to go ahead later at night as jet dryers got on track, but then a new shower dashed any hopes for the fans waiting to see some activity. 

Weather forecasts show only 20 percent chance of rain for today, although the temperatures will be low. Sprint Cup cars will be the first to hit the pavement for their final practice and lay down some rubber before the Nationwide Series race.
